Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the operation schematic diagram of the utility model；
Fig. 2 is the perspective view of filter-portion in the utility model.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The utility model is further elaborated.For thorough explanation the utility model, one can be related in following description
A little specific details.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields makes
With these descriptions herein and state that the others skilled in the art into fields can more effectively introduce their work essence.
Referring to Fig.1, Fig. 2, the first host 10 and the second host 20；Second host 20 is connected with the second motor 40；
First motor 30；The first motor 30 is connected with the first host 10；Second host 20 and 60 phase of gs-oil separator
Even；The gs-oil separator 60 is connected with safety valve；The gs-oil separator 60 is also connected with solenoid valve 70；The electricity
Magnet valve 70 is connected with intake valve 140；Described 140 one end of intake valve is connected with filter 130,140 other end of intake valve and institute
The first host 10 is stated to be connected；The gs-oil separator 60 also passes through cooler 90 and oil strainer 110 and the first host 10
It is connected；A thermostat valve is also arranged by the cooler 90；The air of the gs-oil separator 60 passes through pressure maintenance valve
It exports to user terminal；First host 10 is connected with the second host 20 by controller；In the gs-oil separator 60
And first be also arranged a return check valve 80 between host 10.
The utility model uses driving motor of the frequency control motor as the first host 10 and the second host 20, beneficial
Effect is any speed-ratio regulation being able to achieve between the first host and the second host to match the variation for applying operating condition.And first is main
The utilization rate of the first host 10 can be improved in the design that machine 10 is connected with intake valve 140, filter 130.First electricity of embodiment
It is additionally provided with oil pump 50 on machine 30, wherein the power axis connection of oil pump 50 and first motor 30, lubricating oil is controlled by oil pump 50
First motor 30 is injected, guarantees that first motor 30 works normally, while not needing extra means control oil pump 50.
The gas mixture after compression is drained into oil eliminator 60 by the second host 20 in the utility model, carries out oil gas point
From；Gs-oil separator 60 is connected with safety valve, and when gs-oil separator internal pressure is more than allowable pressure, safety valve unlatching is played
Decompression protection effect；Solenoid valve 70 when compressor shutdown unloads, can needed the pressure releasing in gs-oil separator 60,
The pressure-air in gs-oil separator 60 is exported to the air entry of the first host by the movement of solenoid valve 70, balances suction air pressure
Difference；In addition, pressure-air is opened by solenoid valve 70, it is conducted to 140 internal control gas circuit of intake valve, intake valve 140 is closed,
Separate air and is sucked into the first host 10 from air intake filter 130.Cooler 90 and thermostat valve, the wherein effect of cooler 90 are
The lubricating oil for dividing device 60 to separate from oil gas is the oil of high temperature, reduces oil temperature through subcooler 90, thermostat valve be adjust into
Enter the oil mass of cooler 90, to control the oil temperature come out from cooler 90；Oil strainer 110, lubricating oil is from 90 He of cooler
Thermostat valve comes out to mix enters oil strainer 110 later, and by contaminant filter, lubricating oil passes through oil pump 50 again and injects the first host
10, to complete entire circulation.Mist of oil in pressure-air is separated and retains the lubricating oil separated by gs-oil separator 60
In gs-oil separator bottom, flowed among the first host 10 by return check valve 80.
When specific works, first motor 30 drives the first host 10, and the second motor 40 drives the second host 20, and air is logical
Air intake filter 130 is crossed, is sucked into the first host 10, the first host 10 injection lubrication while compression by intake valve 140
Oil enters the second host 20 through being vented after overcompression, gs-oil separator 60 is discharged to after the compression of the second host 20, and safety valve rises
To the effect of overvoltage protection.After gas mixture separates in gs-oil separator 60, air by pressure maintenance valve export to
User terminal.Oil enters cooler 90 after the separation of gs-oil separator 60, and the flow of cooler 90 is entered by temperature control valve regulation,
The oil temperature for reaching control lubricating oil injects the first host 10 using oil strainer 110.This technology is characterized by, the second electricity
The revolving speed control of machine 40 is determined according to the pressure at expulsion of the first host 10.Controller is one default according to different application operating condition
The target exhaust pressure P1 of first host 10, when pressure P is actually higher than P1, the second motor 40 improves revolving speed, when pressure P is lower than
When P1, the second motor 40 reduces revolving speed.
According to above-mentioned principle, the utility model can also be made appropriate changes and modifications to the above embodiments.Therefore,
